PRINTING- ERESS.

Application filed June 4, 1923.

The present invention pertains particularly to printing presses of the type employing an impression cylinder provided with a plurality ot' impression surfaces, and a plurality ot printing (plate) cylinders, said printing cylinders co-acting with all oli the impression surfaces in muti-color printing and being capable ot autonuitie` alternate retraction when the machine is adjusted for printing separate jobs 'for each printing cylinder.

An important object is to provide an organization of elements, whereby in heavy presses of this character, the shittable printing-cylinders will be advantageously counterbalanced, whereby the mechanisms may be nicely adjusted and Will operate with dependable precision, and whereby the machine .ll possess great durability.

'ther object is to provide, in connec- 3, lll7 tion with such an organization of elements, iil proved controlling devices Jroi controlling the shitting ot the printing cylinders, and prcilcralily in connection with automatic sheet-ieed'ing;i mechanisms, sheet-controlled d, es which automatically control said control devices, whereby the control of the retraction of' the printing-cylinders and their return to the printing position'is rendered autoniiatic. To facilitate an understandingl et the machine from the detailed description which follows, it may be stated preliminar-ily that the preferred construction shown the machine con'iprises: a large impression or tyn'ipan cylinder provided with tivo impresps, each having' associated Workices (grippers) a pair of print- L, ind-ers which are provided with dile hearings, or journal-boxes; a countei 'i ance spring connected with and tendiup to lift each journal-hon; a normally staiionizry tivo-(olor Work) rock-shaft below nach irintingt-cylinder having angularl y adjustable mid-sections equipped With eccentrirs. the angular adjustment ot said ond-smtiens serving to properly position the eccentrica; eccentric rods allording positive connections between the eccentrics and journal-boxes or carriers; a lined actuating ni, or carrying arm, on each rock-shaft; a par# of periodically oscillated actuators iourna led on each roch-shaft, one of said if,.ti,iatoii':l: corresponding in its timing with one or the ir pression surfaces ol the tympan cyinaer and the other with the other; coupling-links, or control members preferably u'iounted on the lined arm (on each Serial No. 643,255.

ide) and serving to couple the xed arm to either oscillating actuator; a feed-mechanism and asoeiated control mechanism corresponding with the related impression surface to wiiich said feed-mechanism feeds sheets, the control mechanism associated with each feed-mechanism being' adapted to successively trip the printing-cylinders to permit the corresponding impression surface to pas the printing cylinders in case of mis-feed; and inter-acting control means -whereby the cylinders retracted as a result olf a mis-'feed at one feed-mechanism will be held at retracted position longenough to permit the passage of the other impression suri'ace in case of mis-'feed at the other feedmechanism. Thus, it Will be understood that there is associated with each feedmechanism a control mechanism which is automatically controlled When the sheetfeeding is done automatically. llVhen the sheet-feeding is not done automatically, the operation ot the control mechanism may be non-automatic, if desired. That is, the tripping; may, in such case, be manually controlled.

It may be added that by simple adjustment, the machine may be set to operate lior independent jobs (one-color Work), each ting cylinder being then automatically acted, in proper sequence, to permit the noncorresponding impression surface to pass without contact.

The invention is illustrated in its preferred embodiment in the accompanying drawings, inv Which- ;Tigure l is an elevation oi' a complete press structure embodying;- the present invention Figure 2 is a side elevation oit' the upper portion or the press, showing an arrangement ot trips cio-operating; `With the feeding` mechanism and operative ennuis-feed;

The press illustrated in the drawings is provided with a suitable 'trame worl 25, in which is rotatably mounted the large impression cylinder 2G, which receives paper trom two feeding devices 2T and 28, preferably mounted on opposite sides et the press. Feeding device 27 simplies paper to the impression roll 9.6 through the intermediary ot the transfer roll 271. Feeding device 28 feeds paper directly to the impression roll 26. The 'feeding devices QT and 2S are so timed as to ileed paper alternately, when both are operating. at intervals ot '1800 on the impression cylinder 26. Cooperating with the impression roll 26 are two printing rolls 29 and 3G. rotatably mounted rcspectively in shi tahlv mounted hearings or carriers 3l and 32. The carriers 3l and 32 are slidaloly mounted in similar sets of guides 337' and each ot the print-ing cylinders is counterhalanced or vieldingly held upwardly against the impression cylinder 2G oy a suitable coil spring 34ract-ing against hea-ds 35 mounted on rods 36 suitably secured to the carriers 3l and 32. The carriers 3l and are adjustahly connected by links 37 and 3S to the eccentric blocks 39 and 40. l/vitliin the eccentric block 39 is rotatably mounted an eccentric al, and in the eccentric hloch a similar eccentric rlhe eccentrics el and 2 are mounted on short shatts and il in a manner more liully liercinatter described. in the press illustrated in the drawings, two printing cylinders may be employed in printing on sheets ted Afrom iboth lceding devices, tor example as in two-color worl. In such worlr, the printing cylinders are normal he.d in engagement with the impression cylinder 26. and means are provided such that, when both printing cylinders are in operation, a misteed on either feeding dcvice will cause a downward movement and disengagement otI each ot the printing cylinders in succession tor the proper period oi" movementot' the imin'ession cylinder 2o'. The printing cylinders are then successively moved into engagement again with the impression cylinder 26 in time to print upon the nent sheet Ated trom the other 'feeding device.

ils will he hereinafter described, the means tor the control ot' the printing cylinders are so arranged that either printing cylinder may he use-d alone with one ot the 'feedingl devices, the other printing cylinder being;- then prevented from engagen'ient with the impression cylinder., or the two printingcy"- inders may he used independently.y each i ith one of the feeding devices and printing independently a diii'erent job.

As the various parts and elements constituting the necessary control mechanism are substantially duplicated 'l'or each olf the printing cylinders 29 and Si?. to avoid con- 'if'usion and eomlgilication elE the drawi' t those involved in the operation ot only o e ot the printing cylinders are shown in do tail. A similar set olf parts in reverse position on the press is provided lor the other printing cylinder.

Stud sliatt il-3 is coupled te a shall' lil which is longitudinally aligned with it lijf means ot a suitable coupling which formed as a sleeve d5 with a projecting yoke i1:6. each side ol which is provided wi l1 a threaded holt Ll-j'. The ends ot the halts i7 engage a pin 'which projects 'from the eccentric lll. By means et the liiolt, lf/l" the relative angular positions oi the ,.iatt i3 and the stud shaft 1li-l can lie closely a )Usted Keyed to the shaft 43a is a carrier leve #lll or linedly secured actuating arm having ex:- tended. sleeves 59a on eacli side. The move-- ment ottliis carrier lever causes movement .'t't 'st-3U' and with it et the eccen controlli the carrier for the roll 29.. iat the sides of the carrier lever 4:9 the operating levers 50 and 5l, respecti. ly, are pivotally mounted on the extended sleeves liulos. These levers 50 and 5l are periodically oscillated on the sleeves 119% the former through a link 52 from a cani follower a3 lll() llfi pivoted on shaft 54 and the letter through a link by cem follower 56 mounted. on shaft 57. Ginn followers 53 and 5G lfire provided with pins which project into n suitable cani race on the com Wheel 59 inounted on n counter-shz1ft (Si) constantly driven through gears Gl ind from the mein drive shaft lt will be notec` loni the drawings that the pins projecting the een followers 53 :ind 5G, respectively, into the cani rece on the ciun Wheel 59 are substantially die nietiicnllvY og ',\posite7 so 'that they are oscillntet bv the coin et 1800 intervals. 'lfhese intervals :1re so adjusted by the trein of gearing' es to correspond to llOO intervals of the rotation of the in'pression cylinder 2d .lt will thus be zippers that the control levers o() und 5l. :ire oscilleted et intervals eorrespoinling` to 180o intervals of the rotation of the impression cylinder il" the proper period in its oscillstion, either of the con il levers 50 or 5l may be interlocl-:ed with the carrier leveie119 by means hereinafter fully described..

l'he interlocking' or coupling; of the oscilloting operating lever 50 with the carrier lever i9 is primarily effected by ineens of :i control member or couplingmember Gil pivoted et neer one end of the carrier lever 4:9. t this end, os is apparent from the dreivilngs, the carrier lever i9 expands fanwiso. 'lfhe operation of this control lever is determined by second srv lockingl devices, the operation of which is hereinafter set forth. rl`his control member @el is provided with an inner cui. Yed surface del in which is fori-ned a. notch Gel". llt its end, the oscillatin.4 lever 50 is provided With n. projecting` pin 50, which rides over the curved surface Gl of the control member dil when the ietf ter is in its norinol inoperative position, ns shown, for iz-:nniplo7 in Fig. 3. ln the interlocking position of the control member 64:, the pin 5()A engages in notch Gil", es shown in Fig. 1L, the oscillating;- lever 50 and the cerrier lever 41:9 being tliorebj,7 intoi'.'locl cd. coil sprl" O 66 between the control ineinber (il undv the carrier lever 4:9 tends to force the control member @4l inwardly into interliiicliingr position. ln n similar manner, n second control, nien'ilier G7 rovided on the opposide of the carrier lever e9 and it cooperates in :i similar manner with the os-` cillnting;` lever 5l.

Associated with each of the control meer Jers 64e und 6l aire corresponding` latch levers (lll, resp" etively. rlllie latch lever (38 pivoted et en. the carrier lever L9 and is prov'f` l with :i downwardly depending` erin 68 which. when the control. member 6% is in its normal inop i'sitive posit-ion as in l!" Il? engages :i shoulder 64C formed on the control niemeer 6, il. coil spring ll extends between the control member Gel. and the latch lever 68, tending` to hold the erin 6&5 of the latch lever G8 in engagement with the shoulder Gil-ff, The latch lever GS thus norinef i serves to bitch the control member in inoperative position, so that the oscillating lever 5'() may oscillete freelj,1 Without nrrj/ing with it thev carrier lever 49. @n the opposite side of the ceri'ier lever 4:9, the latch lever 69, which is constructed similarly to the latch lever G8, oper-etes in a like manner.

lt is thus apparent that the operation the eerrier lover i9 end with it of the printii roll 2.9 is controlled for period of l'llc or the movement of the impression roll bv the control member @d and the lnteh lever GS and for the otherl period of 180 of the rotation of the impression roll 26 by the control member 67 and the latch lever 69.

of the printing rolls being' thus .nitide clear, the properlyv timed operation of these control devices from the feeding nieehenisni will non' be considered.

Considering' first the feeding device ninnbered 27, and referring more particularly to llgs. i and l?, when e sheet of peper .is j 'noperly fed by the feeding device 2?', passes between a trip linger 72 end e plete "l, in which is forlnet` :1 notch Til. rlhe trip ling/er Y2 is loosely connected at one end with nn oscillating' lever 75 ndjnstnbly yonnted on e short orb-or T6, 'this arbol.' tink.; snitebl'gf journoled in e supporting; bracket Y?. Secured to this arbor is another. lever 78, the end of which is connected. bv neens of e link 79 to e lever cani follower 80 mounted on e stud shaft 8l. This cani follower is provided at one end. With :1 roller 82 Which follows he surface of csi-in rlhe lever 8O is provided with nn additional erin 8e which is connected by ineens of n linl; 85 with e bell crank lever 86 pivoted on the supportingfreine of the machine. A coil spring- 87, connected between one erin of the bell crank 86 rind the supporting` freine of the machine, tends to hold the cern follower S2 of the com lever 8O in onge-ge ment With the surface of cani 88. 'llie bell orenl lever 86 is connectedby ineens of n. link 88 with n, push rod S9, the function of which will be hereinafter explained. lt will. be nppzirent that the rotation of the cani 5355 censos e periodic oscillation of the lever can.; follower 80 end with it of the arbor To. This results in n periodic to-:indY-froino-ve nient of the trip lino-er 7% which continues as long' es paper is fed progerlf,7 between it end the notched. plete 7 At the seine time, the push rod 8l) is periodically swung beclivnrd and. forward by ineens of tlf bell ci l: lever 86.. The cun snrfece of n second rote. ing com 90 engnffes :i roller lll et one end of the bell crank lever 92 pivoied to the suplOltlg from@ of the machine et 93. il rtg lill other end this bell crank lever is provided with a push plate 94 which, under suitable conditions, may engage the end of push rod 89. rIhe bell crank lever 92 is held against the surface of the cam by means of the coil spring and consequently the# bell crank lever 92 is likewise periodically oscillated. The normal oscillations of the cam follower lever 80 by means of the cam 86 and of theI cam follower lever 92 by means of the cam 90 are so timed that the push rod 89 is not normally engaged by the bell crank lever 92. The periodical oscillations of the cam lever 80 and the bell crank lever 92 are so timed as to occur as each sheet to be printed upon is fed by the feeding device 27. to the press; that is, once for each revolution of the impression roll 26.

ln case` of mis-feed, however, the smooth surface of a sheet of paper is not interposed between the trip linger 72 and the notched plate 7 8, with the result that the trip finger, after its back stroke, is retained against forward movement by the notch 74. Nhen this occurs, the cam lever 80 is held away from the lower portion of the race of the cam 88 and, through link 85, bell crank lever 86 and link 88, the push rod 89 is held in position to be engaged by the downward stroke of the bell crank lever 92. llhe downward movement of the push rod 89 is communicated to a lever 96 mounted on shaft 96a. This movement of the shaft operates lever 96h, connected with the shaft, resulting in an upward pull on the link 97, which is connected to an oscillating lever 98 secured to the shaft 99. Upon the same shaft is mounted a projecting lever 100, from which depend two links 101 and 102, to the ends of which are secured the loops 108 and 104. Within these loops lie the ends of the push rods 106 and 107, respectively. The other end of push rod 106 is connected to a lever 108 secured to shaft 109. As will be hereinafter pointed out, this lever 108 controls the initial operation of the latch lever 68 mounted on the carrier lever 49. The other push rod 107 is connected at its end to a similar lever 110 secured to a sleeve 110?L on shaft B 109, the operation of which lever substantially duplicates that of lever 108 and will consequently not be more fully hereinafter described. 1W hen the trip linger 72 is operated bv a misfeed, as has already been pointed out, the link 97 is raised for the period of dwell of the cam 90. rlfhrough the mechanism just described, that is, the link 97, the oscillating levers 98 and 100 and the links n 101 and 102, the push rods 106 and 107 are raised for corresponding periods. The rise of the end of push rod 106 brings it into position to be engaged by the hammer 111 mounted on the cam follower 112, which is pivotallyl mounted on shaft 118. Gain follower 112 is operated by cam. 11.4 1nounted on the counter shaft B 60, which is driven by suitable' gearing from the drive shaft 68. A second cam follower 116, operated by the same cam 114, is provided with a similar hammer 117 which engages the end of the push rod 107 when the latter is raised. The cam followers 112 and 116, both of which are mounted on the shaft 118, are so disposed as to operate with an angular difference between them corresponding to the angular difference in position of the printing rolls 29 and 80 with relation to the impression roll 26. The cam follower 112, through the lever 108, initiates downward movement and disengagement of the printing roll 29; and the cam follower 116, through push rod 107 and lever 110, performs a like function for the printing roll 80. By the proper timing of the cam followers 112 and 116, a proper timing of the operation of the printing rolls is in part secured.

vWhen the push rod 106 is engaged by the hammer 111 on the cam follower 112, it actuates the lever 108 and with it the lever arm 108, also secured to shaft 109. A roller 108b on the lever 108L engages the arm 68b of the latch lever 68, thereby throwing the end of the arm 68a of the latch lever 68 out of engagement with the shoulder 64c on the control member 64. The latter is thereby unlocked, and, when the roller 50a on the oscillating lever 50 comes opposite the notch 64b in the control member 64, the latter moves upwardly into engagement with the oscillating lever.

At the same time that the lever 108 is operated by the push rod 106, and with it the lever 10821, a roller 119 on the former engages the projecting end 120 of the long arm of lever 121, vhich is pivotally mounted on shaft 122. The lever arm 121 is provided with a shoulder 121b which engages an interlocking shoulder 49a formed on the carrier lever 49. The shorter arm 121EL of lever 121 projects downwardly and is engaged by a coil spring 128, which normally tends to hold the shoulder 121" on. the opposite end of the lever in engagement with the shoulder 49a. These interlocking shoulders 121b and 49a are engaged in the normal inoperative position of the carrier lever 49, but are disengaged by the movement of the lever 121 resulting from the operation of the push rod 106 at the same time that the latch lever 68 is operated to permit release of the control member 64. Thus at the saine time that the carrier lever 49 is interlocked with the 0scillating lever 50 by the control member 64. the carrier lever is released from engagement with the lever 121 and its movement is permitted.

A similar set of controls is provided ou the opposite side of the carrier lever 49 for the operation of the control member 67 on the opposite side, these controls being effec- Ulli movement operates a set of push rods, similar to the push rods 106 and 107, one of these push rods causing the operation of printing cylinder 30 in the manner which has just been describedy for the operation of the parts under the control of the push rod 106. The other push rod, which plays a function similar' to that of the push rod 107, has its movement transmitted through a sleeve B a on the shaft 109 to a lever' 133 (see Figs. 5 and 6) which lever controls the operation of the control member 67 in precisely the same manner as the lever 108 controls the operation of the control member 64. rEhe control member 67 then loelrs the operating lever 51 into engagement with the carrier lever' 49 and a set of movements preois-ely similar to that which has already been described then takes place, the printing cylinder Q9 being depressed and again returned to its proper printing position. Since the cam follower 56, which operates the oscillating lever 51, is so timed as to operate 180O behind the cam follower 53, the sequence of operations is 180O on the impression cylinder later than the series of operations controlled by the control member 64. In other words, the operation as to each of the printing cylinders is timed at intervals corresponding to the intervals separating the feeding of the sheets from the feeding devices 27 and 28. n

When, by reason of a mis-feed'of the feeding device Q7, in two-color operation, the roll 29 has been depressed, if there is a mis-feed at the other feeding device 28, special means are provided for maintaining the printing cylinder 29 depressed for the period of 180O of the rotation of the impression cylinder corresponding to the second misfeed. It will be noted from the drawing` that the rising movement of the link B 97 controlled by the trip on the feeding` device 28, operates not only the lever on B 98 on the shaft B 99 and through it effects the depression of the printing roll 30; it also operates a linlr 133 which is cont ed to :i lever 134 mounted on shaft 135 posi this shall. oned a rod 136, the lower end of winch is secured to a lever 137 mounted on a shaft 138. rt the upper end of the rod 136 a spring 140, secured at one end to the end of the rod and at its other end to a cross bar 141, tends to pull the rod 136 outwardly and upwardly into such position that the shoulder 136a formed thereon may be engaged by a pin 134L mounted at one oud of the lever 134. 1n the normal i1". J' position of the carrier lever 49, a shoe 139 mounted on an extended arm of the carrier lever presses against the rod 136 and holds 1t in a position in which the shoulder 136a cannot be engaged by the end of the lever 134. l/Then, however, the shoe 139` on the carrier arm 49 no longer engages the rod (.1 below the shaft 99. Near 1", eimer 136 by reason of the movement of the carrier lever 49 induced by a misfeed in the feeding device 27, the rod 136 is pulled out by spring 140 to a position in which it i'nay be engaged by the pin 1343. 1f at this time a misfeed in the feeding device occurs, has previously been stated, movement is transmitted through rod 133 to the lever 134, resulting` in a downward movement of the end o f the lever 134, the end of which engages rod 136. The latter is forced downwardly and with it the end of the lever 137 to which the rod 13E secured. 'ifo the other end of 'this lever is secured one end of a hnl; 142. the other end of which is pivot d to a lirh l-l) which in its turn piveted to a cani 'ollower 144 mounted on the shaft 128l ou position to be engaged by the pin 143 ou the link 143 when the latter is raised. Y`When the control member 64, is in the position shown in Fig. 4 by reason of a misfeed on the feeding device 27, the movement of the lever 137 resulting' from a misfeed in the feeding device 28 lifts the end of the liulr 143 and causes the pin 1432l to engage the arm 147 of the lever 147. The periodical to-and-fro'movement of the linl; caused by the cam follower 144, occurring at this time, causes the depending arm 147') of the lever 147 to be retracted, thereby dre-wing down the hooked arm 147 into engagement with a pin 64C on the Control member 6-1 tud forcing the control member downwart' The latter' is thereby released from engT ment with the operating lever 50 u und brought into a position in which the arm 68'l of the latch lever 68 engages the shoulder on the control member and loelrs it into its normal inoperative position. rit the same time that this occurs, the movement of the lever 147 is transmitted through a linl; 11118 to a lever 149 which is secured to shaft 151. rfhe movement of' the lever 149 is transmitted through the shaft 151 to a lever arm 152 (see Fig. 9). Prior to this movement, the latch lever 69 mounted on the opposite side of the carrier lever 49 from the latch lever 68 and co-operatinn` with the control member 67 in the same manner that the latch lever 68 oo-operates with the control member 64, has been interlocled with the control member. @ne arm of the latch lever 69 projects into the path of movementof a roller 153 mounted on the arm 152. The upward movement of this arm, induced by the movement of the linlr 148 resulting from the movement of the lever 147, raises the arm of from j if. j.

the latch 69 and unlocks the control member 6'?, thereby engaging the carrier lever 4S) with the operating lever 51. rlhe control member 64 being locked in inoperative position and the control member 67 being in its operative position7 the carrier lever 19 partakes of the movement of the latter lever for a complete oscillation, resulting in a depression of the printing roll 29 during the period of operation of the impression cylinder 26 corresponding` to the misfeed in the feeding device 28. ln the rising movement of the carrier lever 419 during the oscillation of the operating lever 51, the control member 6*? released from the operating lever 51 in the manner already described for the normal release of the control member 64 from the operatin member 50. That is, the depending` arm of the control member 67 engages a lever 154 disposed on the opposite side of the plane of the carrier lever L19 from the lever 181 and operating in precisely the same manner through e link from a cam follower 156 controlled by a cam 157 on the shaft B 60.

1f the first inisfeed had been on the feeding device 28, it would have been communicated through the link B 97 and the lever B 98 to a push rod (not shown) operating on the lever 133 on the sleeve B 110 on shaft 109, and simultaneously would have operated the lever 121 to release the carrier lever i9 in the manner already described for the lever 106. ln the manner already described for the yoperation of the operating ever 56 and the control member 611, the operating lever 51 and the control member 67 would have been affected, resulting in a downward degression of the printing` cylinder 29 during the period corresponding to the oscillation of the operating lever 51; that is, to the O period of rotation of the impression cvlinder 26 corresponding to the time of fceoing b v the feeding device 28. lf at this time a misfeed had occurred in the feeding device 27, it would have been communicated through the rod 97 in the manner already `described to the lever arm 98 on the shaft 99. rlhis would have been communicated through a link 160 to a lever 161 mounted on the shaft 135. This lever cooperates with a rod 162 in the same manner that the lever 134 co-operates with the rod 136v As result of the downward movement of the rod 162 resulting from the movement of the lever 161, the lever 163 is actuated, drawing the link 163a upwardly and with it the link 164i which is secured to the cam follower 165 mounted on the shaft 128s. This cam follower 165 corresponds in its Ioperation to the cam follower 14111 previously referred to. The cam follower 165 co-operates with the cam 166 on the shaft B 60, which causes a periodical oscillation of the cam follower and a two-and-fro movement of the link 164i. When the linlr 164e is raise by the lever 163, a pin 167' secured to its end, is drawn up behind a depending arm 168b of a lever 168 pivoted to shaft 146, this iever corresponding in opera- 70 tion and function as regards tue control member 67 to the lever lfli' as regards the control member 64%. ln Q these parts are inost clearly shown, the control member in this ligure being shown interlocked with the operating lever 51., the downward movement of the carrier lever L15) being about to begin. Under the conditions just"describedr the carrier lever 4-9 would be at the bottom of its movement, and the pin 6T on the control member 6T would be in position to be engaged bv the hooked end of "he le 'er 1.66. rlhe movement of the l 166 relever sulting from the movement the link 1 would thereupon release the control men 6? from the operating lever 5l. permit," the latter to oscillate freellv. The moven of the lever 166 would simulteneouslv canse a movement of the link 169 connected to the lever 170 mounted on the `sleeve O mounted on the shaft .its :een from 16, the movement of the lever 170 is communi.- cated 'l the sleeve 156 to a lever 1.71

:trough irovide-d with a projecting pin 172. This is the latch movement of the ,lever 1171 tr lever 66 which locks the control niemeer 6-1 out of engagement with the vopere-.ting lever 50, permitting the control 1n mber to enf the operating lever 5G. is a result of tins movement, for the next period of 18Go of movement of the impression roll the carrier lever 119 partakes of the oscillatonvv movement of the operating le er 5G, resulting in a second depression of the printing cylinder 29 for that period.

ln order to adjust the device for single color work, three adjust-ments are mede at each end of the press, the nature of th se for one end of the press being shown in the drawings, the duplicate set of elements for the other end of the press not being shown. ,ln operating single color work, the printing cylinder 29 operi on y in conjuimtion with the feeding device 2l' and depressed for each period of operation correspending to the feed from the feeding device 28. lt will hence be apparent that the control member 67 must tile opere-.ting lever 51 on each oscillation of the .latt in order to depress the printing roll 2 ing the proper period; thet the cylinder 29 must be in its operative posit i during the period corresponding to the from the feeding device 27; and that trip controlled from the feeding device must throw the printing cylinder 2S) out whenever a misfeed occurs in the feeding device 27.

By reference to 9, 12 and 13, it will "t 14'3 passes through llt) be seen that a short sha-r the carrier lever 49 at a point between the two upper arms of the latch levers 68 and 69. @n the side o1 the carrier lever fl-) upon vvhieh is mounted the control member (-ll there is secured to the shaft 178 a l-ever arm 1711 on the end of which is mounted a spring'- A.ressed plunger 17 5 provided with a handle 176. Tivo depressions 177 and 178 are termed in the carrier lever i9 into Whichthe spring-pressed plunger 175 may engage, the former when in its inoperative posit-ion and the latter when in its operative position. To the opposite end of the shaft 178 are secured two eccentrics, 179 and 180, respectively. 'llo the latch lever 69 is secured a pin 181 positioned to be engaged by the eccentric 180. The eccentric 17 9 is adapted to the lever 1.21. ln its normal inoperative position, the plunger 175 on the lever 171- enters the depression 177 and the vflat sides oi the eccentrics 179 and 180 come opposite the respective parts 121" and the arm of latch lever 69, so that the latter elements are not atliected by the eccentrics. 1n changing to single color Work, the lever 17d is turned until the plunger 175 engages the depression 178 as shown in Figs. 12 and 18; the eccentric 179 engages the lever 121 and holds it out ot' interlockingengagement with the lever l?, and the eccentric 180 engages the pin 181 on the latch lev-er 69, holding' it in a position such that it cannot engage the locl'- ing shoulder on the control member 67, is a result oiE this adjustment, the lever 121 cannot interlock with the carrier lever 1179 and the latch lever 69 cannot interlock vvith the control member 67.

The second adjustment to be made is shown more clearly on Fie: 16. The pin 17 2, which is pushed outwardly by a spring 182, is retracted into a cavity 188 formed in the end of the arm 171 by means of the protruding` handle 184. The pin 185 termed on the plunger pin 172 passes out through an opening- 186 in the back ot the cavity and by rotation of the handle 184 the plunger pin 172 is held in its retracted positioi a result of this adjustment, the operation o' the lever 171 cannot atleet the extended arm ot the latch member 68 vvhen the operating .lever 49 is in its lovvermost position.

rlllie third adjustment is the movement oli the lever 1511 (which operates ivith respect to the control member 67 in the same manner the lever 181 operates with respect to the control member 6st) to such a position that it camiot engage the depending,l arm olf'th-e control member 67. This is ellected by extending` the link 155 (corresponding to the link 13G) beyond its point of engagement with the lever 15d and forming a notch or other suitable means for connection with the lever in the extended portion, as at 189. ln making adjustments 'for single color Work, the normal connection between 'the Vhooked arm engages the pin opposite end ot the lever and the link 155 is disconnected and a neu7 connection made in the notch .189. `he lever 15/1 is thereby pushed back to a position in which it entirely out oif the patl. olj the depending` arm ot the conn :"1 trol member 67.

lt will thus be apparent that in norn al operation in single color vvork, with these three adjustments made, the control member 67 lever 51 and the carrier lever con'eipiently periodically oscillated, the o.k 'ilhitions correspoiiding to the periods ot tie-ed trom the i'ieedinp` device 28. rllhese oscillations brine; the printingl cylinder 2i) bark into operating position dining` the periods correspomliin to the feed from the t'ef mg" device 27.

When there is a misteed trom the itcedin device f the sequence ol operations i" t iat alreacy described for those instances in which a misteed occurs on the 'feedingdevice 27 immediately after a` misteed on the feeding device 28. At the time the mis'reed occurs, the operatinp lever 531 has brrmg'ht the carrier lever 49 down to its lowermost position. 'l'he rod 162 is in position to be engaged by the lever 161, which is operated as a result oi the mis'lecd. The movement ot the rod 162 operates the lever 168 to raise the link 163 and the link 1611. The j il?) then engages the depending* arm et the lever 168 and the to-antl-tro movement ot the l nk 164,- draivs the lever doivnivardly, so that its Y 37e on the con-- trol member 67, pulling` it downwardly. im The simultaneous operation ot the lever 168, however, is not effective to cause the latch member 68 to unlock the control inen'iber and permit its engagement with the carrier lever by reason ot the Withdrawal of the lv pin 172 trom its engaging position, as ex plained in connection with l? ,16. rlhe control member ren'iains in inoperative position and the operating` levers oecillate treeljY Without moving` the carrier lever 'Lt-), which. remains in its lovvermost posi. ,n until the operating` lever 51 again re ches its levier most position. Betere this time the rod 162 has been released and raised by its spring; 162g, so that the control men'sber again permitted to engage the carrier The latter then resumes its normal oscillating` movement.

1t is, et course, understood that an entirely similar set et operations takes place at the ifor the control oll the printing` cylinders 80,'so to print dnring the period oli operation corresponding to the leed ot sheets Yfrom the feeding device 28. lt is thus apparent that in single color operation, the two printing rolls may print separate jobs, one on sheets lied Atrom the 'feeding` device 27 and. the other on sheets 'led r1 im the feeding device ln the printing` press illustrated in the 130 drawings, means are provided for the depression of the inlting devices simultaneously With the printing cylinders 29 and 30. In

the drawings, the mode of operation of this means .is illustrated, particularly in connection with the inliing` devices operating in conjunction with the printing cylinder 29. l-aiticular reference may he had to Figures l, 8, 10, and 1l, the latter ligure showing a sectional detail on the line ll-ll of l0.

The entire inlring mechanism operating in conjunction with each printing cylinder is mounted upon a frame Work 190 movable longitudinally of the press. Vertically ,la slidahle. upon each carriage 190 is a support '191 for the ink distriloutingrolls 192. On cach sine of the press, each support 191 is provided with a hardened hlocli 192a in which is a horizontal slot 193. A coil spring` 94: on each side of the press extends from a projection 195 on the carriage 190 through another projection '196 on the support 191 and exerts its force upwardly against the latter, tending to hold it in raised position. A cranlt pin 197 secured to a crank 198 on the shaft l99 journaled in the carriage 190 enters thepuide slot 193 at each side of the n; 191. A lever 200 is secured to the s f i799 within the latter, and from it a link QO'l entends to a lever 202 mounted on a shaft 2( 3, likewise journaled in the carriage Ult), 'llo the shaft 205:3 is secured a sii-.cond lever arm d. From this a linl; 205 ln'evided with a handle 206 extends through and is removably attached to a pin 207 projecting from the eccentric ll on the shaft 4453. ln the form illustrated, a notch is provided in the link 205 for engagement With this pin and suitable means are provided for retaining` the pin in the notch.
